data dir does not exist

[bteb]

this directory is in /mnt/sdcard/emacs
it was installed there by the play store installer,
but for some reason emacs now wants it in /sdcard/emacs
when i copy
cp -a /mnt/sdcard/emacs /sdcard/.
it works
but i don't have enough disk space there
is it possible to configure the location of data dir ?

i ;) emacs !

I seem to be seeing this problem on a Samsung Galaxy Tab 3. But have gotten emacs to start by issueing
cd /data/data/com.zielm.emacs/src; bootstrap-emacs
But emacs is very slow to respond, on the order of 30 seconds to split window.
